require() vs. include()

[Thora_Fan]

I've gone through the PHP docs, and if the answer is there, I'm totally not seeing it. What is the difference between require() and include()? Both seem to do the same thing. It boggles the mind.

From [man]include[/man], second paragraph:

The two constructs are identical in every way except how they handle failure. include() produces a Warning while require() results in a Fatal Error. In other words, use require() if you want a missing file to halt processing of the page. include() does not behave this way, the script will continue regardless.

Always use require() unless you want to handle the case where the file is missing.

I always use require() except for my config file, so I can print a reasonable error message if it's missing. Everything else is a core part of the app, and if it's missing, a fatal error is desirable.
